Green's functions technique for calculating the emission spectrum in a quantum dot-cavity system
TL;DR: Gomez et al. as discussed by the authors introduced the Green's functions technique as an alternative theory to the quantum regression theorem formalism for calculating the two-time correlation functions in open quantum systems at the steady state.
Various approaches to photon antibunching in second-harmonic generation 1
A. Miranowicz,J. Bajer +1 more
TL;DR: In this article, the authors analyzed the most popular approaches to photon antibunching as exemplified in a simple model of second-harmonic generation and found the exact evolution of the fundamental and harmonic fields for initial Fock states with small photon numbers.
Journal ArticleDOI
Photodetection of a weak light signal in various quantum states by using an optical amplifier
TL;DR: In this article, the photodetection of weak light signals preliminary amplified in optical light amplifiers is analyzed quantum-mechanically. And the signal-to-noise ratio for the detector photocurrent is studied as a function of the quantum-statistical properties of the signal and idler waves involved in amplification by using the four-wave mixing scheme.

A phase in a coherent-state wavefunction - is it always irrelevant?
W. Berej,Piotr Rozmej +1 more
TL;DR: In this article, the authors derived the expression for the required phase factor and corrected some errors occurring in the literature, where the authors considered the time evolution of the coherent state wave function and the properties of coherent states.

Use of the squeezed (sub-Poisson) state of light in small-signal detection with preamplification upon four-wave mixing
TL;DR: In this article, the authors proposed an active interferometer for signal amplification of small optical signals for subsequent photodetection, which provides a considerable amplification of signals by preserving their quantum-statistical properties.
